Model-Export and Model-Save: Crash
When the Model Export or Model Save operator is used, "Show by Category" is checked, and then "Advanced" is selected, MB will crash.
- Create a new polygon model
- Go to Model - Export (this recipe will work whether or not model entities exist)
- Check "Show by Category"
- Switch from General to Advanced
Side note: The Advanced and Category options should NOT be visible for these operators anyway. See issue #178 (closed)
